Security Issues
In January 2010, two major security holes were discovered with the Novatel MiFi 2200 which, if properly exploited, could allow a malicious user to obtain the device's current GPS location and security keys. If the malicious user were physically close enough to use the device's Wi-Fi signal, this could give access to the MiFi's 3G connection as well as any other connected devices. Novatel responded that a security patch would be available in February 2010.
The popularity of MiFi devices can also be problematic for corporate network security. Corporations generally expect to control on-site internet access: many use firewalls to reduce the risk of malware, and some enforce restrictions aimed at employee productivity. Personal mobile hotspots may provide a "back door" by which employees can circumvent these precautions.

Famous quotes containing the words security and/or issues:
“I feel a sincere wish indeed to see our government brought back to it’s republican principles, to see that kind of government firmly fixed, to which my whole life has been devoted. I hope we shall now see it so established, as that when I retire, it may be under full security that we are to continue free and happy.”
—Thomas Jefferson (1743–1826)
“How to attain sufficient clarity of thought to meet the terrifying issues now facing us, before it is too late, is ... important. Of one thing I feel reasonably sure: we can’t stop to discuss whether the table has or hasn’t legs when the house is burning down over our heads. Nor do the classics per se seem to furnish the kind of education which fits people to cope with a fast-changing civilization.”
—Mary Barnett Gilson (1877–?)
